¦Á-Ti crystal will appear in the form of crastal in the melt before peritectic transformation,then ¦Á-Mg nucleation that attaches itself to the surface of ¦Á-Ti will occur and the good dispersed ¦Á-Mg phases will be formed. As temperature decreases, As temperature decreases, the primary ¦Á-Mg is formed directly and the small particles of ¦Á-Mg generated by transformation act as crystallization nuclei.![]() |
